Abstract

The fitting comprises a pipe connection with a one-ended connecting head (2) on which a one part full flange (1) is fitted. The connecting head is blunt conically shaped, with the smaller blunt conical end surface forming the transition to the pipe connection. The full flange has a through passage opening, which has a negative profile corresponding to the blunt conical section of the connecting head. The connecting head in the area of the larger blunt conical end surface has an approach limitation (13) for the full flange. The approach limitation connects directly to the larger blunt conical end surface. It is so formed and arranged that the face surface (7) is enlarged through a diameter enlargement of the connecting head.

Description

Die vorliegende Erfindung betrifft eine Schlaucharmatur, insbesondere SAE-Kopfarmatur für Höchstdruckschläuche, bestehend aus einem Rohrstutzen mit einendigem Anschlußkopf, insbesondere SAE-Kopf, sowie einem auf diesem gelagerten einteiligen Vollflansch, wobei der Anschlußkopf kegelstumpfförmig ausgebildet ist und die kleinere Kegelstumpfendfläche den Übergang zum Rohrstutzen bildet und der Vollflansch eine Durchgangsöffnung besitzt, die ein dem kegelstumpfförmigen Abschnitt des Anschlußkopfes entsprechendes kegelstumpfförmiges Negativprofil aufweist.The present invention relates to a hose fitting, especially SAE head fitting for high pressure hoses, consisting of a pipe socket with one end connection head, especially SAE head, as well as one on top of it stored one-piece full flange, the connection head is frustoconical and the smaller frustoconical end surface forms the transition to the pipe socket and the Full flange has a through hole that the one corresponding frustoconical section of the connection head has a frustoconical negative profile.

Bei den bekannten SAE-Flansch-Kopf-Armaturen erfolgt die Befestigung des Vollflansches in der Regel mittels vier Schrauben. Bei einer nicht fachgerechten Montage ohne entsprechenden Drehmomentschlüssel, können die Schrauben zu fest angezogen werden, so daß der Vollflansch zu weit in Richtung der größeren Kegelstumpfendfläche gezogen wird und durch den Anschlußkopf unzulässig aufgeweitet wird. In the known SAE flange head fittings, this is done The full flange is generally fastened using four Screws. In the event of improper installation without appropriate torque wrench, the screws can too be tightened firmly so that the full flange is too far in Is pulled towards the larger truncated cone end face and is improperly expanded by the connection head.

Der Erfindung liegt die Aufgabe zugrunde, die oben genannten Nachteile zu vermeiden und die bekannte Höchstdruck-SAE-Flansch-Kopf-Armatur derart zu verbessern, daß bei einer nicht fachgerechten Montage der Vollflansch nicht aufgeweitet wird und dadurch die Funktion des Vollflansches im Zusammenhang mit dem Anschlußkopf bestehen bleibt.The invention has for its object the above Avoid disadvantages and the well-known high pressure SAE flange head fitting to improve so that at improper installation of the full flange is expanded and thereby the function of the full flange remains in connection with the connection head.

Erfindungsgemäß wird dies dadurch erreicht, daß der Anschlußkopf im Bereich der größeren Kegelstumpfendfläche eine Anzugsbegrenzung für den Vollflansch aufweist.According to the invention this is achieved in that the Connection head in the area of the larger truncated cone end surface has a tightening limit for the full flange.

Die Erfindung basiert darauf, daß eine zu weite Bewegung des Vollflansches in Richtung der größeren Kegelstumpfendfläche vermieden wird und dabei die verbindende Funktion des Vollflansches bestehen bleibt, da die Kraftübertragung zwischen dem Vollflansch und dem Anschlußkopf hauptsächlich über eine, eine schiefe Ebene bildende, Kegelumfangsfläche erfolgt. Lediglich die überschüssige auf den Vollflansch wirkende Kraft wird von der erfindungsgemäßen Begrenzung aufgefangen. Durch die Anzugsbegrenzung wird ferner auch bei unterschiedlichen Anzugs-Drehmomenten der Schrauben eine absolute Planlage des Vollflansches erreicht. Dies ist eine wichtige Vorraussetzung für eine sichere Funktion der Schraubenköpfe, die ohne Planlage dazu neigen abzureißen. Außerdem bewirkt diese eine völlig spaltfreie Auflage der Armaturen-Dichtfläche auf dem jeweiligen Gegenanschluß mit zuverlässiger Abdichtung und ohne Verletzungsgefahr für die jeweiligen Dichtringe. Wegen einer Durchmesservergrößerung des Anschlußkopfes durch die Anzugsbegrenzung wird die Stirnfläche vergrößert, was zu einer erhöhten Standfestigkeit auf dem Gegenanschluß führt. Ferner wird durch die verstärkte Auflage des äußeren Flanschbundes der Armatur sichergestellt, daß auch bei erhöhten Anzugs-Drehmomenten der Schrauben die Gefahr einer Überschreitung der Materialfließgrenze und damit verbundene Deformationen des Dichtkopfes mit der Folge von möglichen Undichtigkeiten vermieden wird.The invention is based on a movement that is too wide of the full flange in the direction of the larger truncated cone end surface is avoided and the connecting function of the full flange remains because the power transmission between the full flange and the connection head mainly over a conical circumferential surface forming an inclined plane he follows. Only the excess on the full flange effective force is from the limitation according to the invention caught. The suit limit will also with different tightening torques of the screws an absolute flatness of the full flange is achieved. This is an important prerequisite for the safe functioning of the Screw heads that tend to tear off without flatness. In addition, this causes a completely gap-free edition of the Valve sealing surface on the respective counter connection with reliable sealing and without risk of injury to the respective sealing rings. Because of an increase in diameter of the connection head due to the tightening limit Front face enlarged, resulting in increased stability leads on the counter connection. Furthermore, the reinforced support of the outer flange collar of the valve ensures that even with increased tightening torques of the screws the danger of exceeding the material flow limit and related deformations of the sealing head with the consequence of possible leaks avoided becomes.

Wie sich aus den Figuren 1 und 2 ergibt, besteht eine erfindungsgemäße Schlaucharmatur, insbesondere SAE-Kopfarmatur, aus einem Vollflansch 1, der auf einen Anschlußkopf 2, vorzugsweise SAE-Kopf 2, aufgeschoben ist. An den SAE-Kopf 2 schließt sich einstückig ein Rohrstutzen 3 an. Der Vollflansch 1 weist vier äußere symmetrisch angeordnete Schraubenlöcher 4 auf und eine mittige Durchgangsöffnung 5. Mit der Durchgangsöffnung 5 sitzt der Vollflansch 1 auf dem SAE-Kopf 2. Der SAE-Kopf 2 ist im wesentlichen kegelstumpfförmig ausgebildet. As can be seen from FIGS. 1 and 2, there is one hose fitting according to the invention, in particular SAE head fitting, from a full flange 1 on a connection head 2, preferably SAE head 2, is pushed on. To the SAE head 2 connects in one piece to a pipe socket 3. The full flange 1 has four outer symmetrically arranged Screw holes 4 and a central through opening 5. With the through hole 5, the full flange 1 sits on the SAE head 2. The SAE head 2 is essentially frustoconical educated.

Bei dem in Figur 1 dargestellten Ausführungsbeispiel schließt sich an die größere Kegelstumpfendfläche des SAE-Kopfes 2 ein kreiszylindrischer Ansatz 6 an, dessen Durchmesser größer ist als der Durchmesser der größeren Kegelstumpfendfläche und des damit eine Anzugsbegrenzung 13 für den Vollflansch 1 bildet. Die Anzugsbegrenzung bildet einen Ringbund. In der Stirnfläche 7 des Ansatzes 6 befindet sich eine Ringnut 8, in der ein nicht dargestellter O-Dichtring einsetzbar ist. Der Steigungswinkel des kegelstumpfförmigen Abschnitts 9 des SAE-Kopfes 2 beträgt vorzugsweise 15°. Weiterhin weist der Vollflansch 1 innerhalb der Durchgangsöffnung 5 zwei Abschnitte auf, und zwar einen ersten kegelstumpfförmigen Öffnungsabschnitt 11, der an den Kegelstumpfabschnitt 9 in bezug auf seine Abmessungen angepaßt ist, und einen zweiten kreiszylindrischen Öffnungsabschnitt 12, der den Rohrstutzen 3 umfaßt und an dessen Außendurchmesser mit seinem Innendurchmesser angepaßt ist.In the embodiment shown in Figure 1 connects to the larger cone end surface of the SAE head 2 shows a circular cylindrical approach 6, the diameter is larger than the diameter of the larger truncated cone end surface and thus a suit limit 13 for forms the full flange 1. The suit limit forms one Ring collar. In the end face 7 of the approach 6 is an annular groove 8 in which an O-ring, not shown can be used. The pitch angle of the frustoconical Section 9 of the SAE head 2 is preferably 15 °. Furthermore, the full flange 1 has inside the through opening 5 two sections, a first frustoconical opening portion 11, which at the Truncated cone section 9 in terms of its dimensions is adapted, and a second circular cylindrical opening portion 12, which includes the pipe socket 3 and on its outside diameter with its inside diameter is adjusted.

Figur 2 zeigt eine zweite Ausführungsform, welche sich von der in Figur 1 gezeigten Form in der Gestaltung und Aufteilung der Durchgangsöffnung 5 des Vollflansches 1, des kegelstumpfförmigen Abschnitts 9 und des kreiszylindrischen Abschnitts 14 des SAE-Kopfes 2 unterscheidet. Dabei ist der kegelstumpfförmige Abschnitt 9 des SAE-Kopfes 2 sehr viel länger als der kreiszylindrische Abschnitt 14. Um das Aufschieben des Vollflansches 1 zu erleichtern, ist in dieser Ausführungsform der Innendurchmesser des kreiszylindrischen Abschnitts 12 des Vollflansches 1 geringfügig größer gewählt als der Außendurchmesser des kreiszylindrischen Abschnitts 14 des SAE-Kopfes 2. Figure 2 shows a second embodiment, which differs from the shape shown in Figure 1 in the design and Distribution of the through opening 5 of the full flange 1, the frustoconical section 9 and the circular cylindrical Section 14 of the SAE head 2 differs. Here is the frustoconical section 9 of the SAE head 2 very much longer than the circular cylindrical section 14 Sliding on the full flange 1 is easier in this embodiment, the inner diameter of the circular cylindrical Section 12 of the full flange 1 slightly chosen larger than the outer diameter of the circular cylindrical Section 14 of the SAE head 2.

Wesentlich bei der erfindungsgemäßen Armatur ist, daß die berechnete Kraftübertragung weiterhin überwiegend zwischen Vollflansch 1 und Kegelstumpfumfangsfläche erfolgt und die Auflage auf den Anzugsbegrenzungsbund 13 erfolgt.It is essential in the fitting according to the invention that the calculated power transmission mainly between Full flange 1 and truncated cone peripheral surface takes place and the It is placed on the suit limit collar 13.
